To all 107i am it may concern Be it known that I, Gusrixv Anonr Scurr- TLER, a subject of the Emperor of Germany, residing at Kandahar, Narborongh Road, Leicester, England, have invented new and u. .itul Improvements in or Relating to Machines tor lileasurin the Shiperlicial Area ot leather and like Materials, of which the following is a specification.

This invention relates to machines :tfor measuring the superficial area of material such for example as leather, cloth paper and the like. i

l The invention refers to machines such for example as the Sawyer type and its object; is to provide such machines with mechanism whereby, in addition to the indication of the superficial area as at present. the thickness or average tl'iickness oi the material may be measured and indicated.

if further feature consists in the provision of means by which the indicated llltltl.-lU'(- ment, both of the area and average thickness of the material, may be stamped upon the latter.

I am aware that arca-measuring machines are already known wherein mechanism has been provided to stamp the material with the indicated area measurement and i do not make any elain'l to this broad feature per so.

The mechanisms comprisii'ig this invention will be hereinafter described in detail and reference will be made to the acco n mnying drawings, wherein Figure 1 shows the mechanism for mensuring and imlicating the thickness oi? the material. Fig. 2 is a side elevation oi? the mechanism for stamping or marking the indicatcd measurements upon the material. Fig. I) is a plan of the stamping or marking mechanism. Fig. t is a front view of the indicator dial and the actuating mechanism in connection with the same. Fig. 5 shows the stepped-edges oi the indicator disks in an uuroiled or straight form. Figs. 4- and 5 are drawn to a larger scale than the remaining figures and like parts are designated by the same reference characters throughout the I will first describe the mechanism accord ing to this invention for measuring and in dicating the thickness or average thickness of the material as it is passed through the machine.

In order to obtain the average thickness throughout the width of the material, one or more ot" the usual measuring wheels (L or, either side of the center are connected by intermediate mechanism with a pointer 1 mo able around a dial .2, or with other suitable indicating mechanism so that when said wheels (1 are raised by the material passing" thereunder said indicating means will be actuated to show the amount of such lift of the wheels this representing the thickness of the material. The thickness measurement is preferably taken from two of the meashring wheels but it will be understood that one, or more than two may be utilized for this purpose it desirable. The two wheels which occupy that position on each side of the center which corresponds to the part of material where the thickness of the latter is apynroximately of the average, are chosen to actuate the thickness indicator, and the intermediate mechanism for transmitting the amount of lifting movement of the said measuring wheels may he of any suitable character. One form of this intermediate mechanism may consist of a centrally pivoted horizontal lever or beam 3 (Fig. i), the length of which embraces the two measuring wheels (z from which the actuation is to be taken. The ends of this pivoted beam 3 are connected by rods 4 one to each supporting arm or lever I) of the measuring wheels in such a manner that when either or both wheels rise the beam 3 will also rise in company therewith. The pivoted beam is supported by an adjustable coupling rod 5 from a lever (3 (Figs. 1 and i) suitably pivoted on a fixed bracket 7 and adapted when moved, by the movement of the beam 3, to rotate the pointer l of the indicator which shows the thickness of material passing through the machine. The indicator lever ('1 may. rotate the pointer 1 by means of a rack 8 which gears with a pinion on the spindle of the pointer, or by other equivalent means, and said lever (l may be returned to its normal position as herein shown by a counterweight 10.

\Vhen more than twi) measuring wheels I! are employed to measure the thickness of the material these would conununicate the amount of their lift or rising movement to an integrating system of levers (not shown) but such as is used in the weliknown Sawyer machines which levers in turn would move the indicator lever 6 in a similar manner to that already employed on machines for actuating; tie area indicator thereof. When only the thickness of material of a uniform thickness is required, and not, as before described the average thickness .Of material possessing a Varying thickness, then one wheel a may be connectcddirect with the lever 43 actuating the indicator or any number of wheels may be connected to one common lever or rocking bar 3 after the manner employed in the bawyermgchine.

I will now describe the means according to this invention for stamping the material with the indicated area and thickness. These means comprise a series of type wheels which may be movable by hand or foot-lever into and out of contact with the material and with which, intermediate mechanism is combined to setor rotate said typo wheels to bring the figures or marks, corresponding to the measurement indicated, into the proper position for stamping. stamping mechanism is not brought into contact with the indicating mechanism until it is required for use, i. 0., not until after the material has been measured, so that during the time measurement of the material is taking place the indicating mechanism is quite free and unrestricted, thus'its delicate adjustment and operationgi-s not in any way interfered with. it the rear of the area and thickness indicator dials, and adapted to be rotated by the spindles otthepointers of said dials are disks,'c ams ole'quivalents. These disks or camsare each furnished on their face with a serics t steps or projections, or with a helical projection or cam edge. By preference a series of steps are made use of and the disks are arranged in the following manner and as shown in Figs. 3 and l. The disk 11 which is to be rotated in company with the pointer -1 which indicates the thickness of the material is mounted rigidly upon the spindle 12 of said pointer so as to rotate therewith. T he other disk 13 which is to be actuated by the pointer which indicates the area measurement is rotatably mounted on the same spindle 12 as the disk 11 but is rotated from the spindle ll of said area pointer by means of gear wheels 15, one oi which is mounted upon the spindle 14 and the other upon the sleeve or boss of the disk 13.

The steps 16 (Figs. 2, 3 and 5) on the disks ll and 13 are of different heights from the face of thesaid disks and representcthe dill'orent figures or indications on the can responding' dials. For example the scale a, Fig. 5, may represent the scale of s uare feet (or other measure) on the area, 1ndieating dial and the rows d, e, f of stepped edges 16 underneath said scale may respectively represent tens, units and quarters in correspondence with the scale 0 on the dial.

in important feature is that the' The stepped edge in row 9' may represent the thickness in any suitable measure such. as fractional parts. As the pointers rotate, the series of steps 16 on the disks move past the end of plungers or slide rods 17- (Figs. 2 and 3) suitably supported in a bracket 18 or other fixed part of the machine frame. Each slide rod '17 is pivotally connected by means of a link or connecting rod 19 to one end of a toothed quadrant or segment 20 pivotally mounted so as to swing at the end of rocking levers'21.

Rotated by the toothed quadrants or segments 20 are type wheels 22 carried at end of rocking arms or brackets 23,which are coupled to the before mentioned roclt levers 21 by links 24: and arranged to more in company with the said rock levers. These rock levers and arms are preferably two number and are fulcrumed on spindles 25 and '26 respectively, the pivoted quadrants :20 and type wheels 22 being mounted. on rods 27 and 28, respectively carried by the ends of the levers and arms. The levers and arms are arranged to be actuated as will be described so as to bring the surface of the type wheels 22 into and out of contact with the surface of themater'ial. Suitable inking rollers or wlleels29 may be provided and rotated in a bath 30 of ink or paint and The ink ,mg rollers are rotated by friction with the in contact with the type wheels.

till

type wheels 22 or they may be driven by I suitable gearing actuated by the segments;

A swinging segment 20 is furnished for each type wheel 22 and drives the latter by means of a, pinion 31 thereon, The segments are turned or rocked on their pivots 27 by mechanism comprising spring 5s, a pivoted and counterweighted rock lever 33 and a connecting link 34. The rock lever 33 is mounted upon a fulcrum 35 supported by the machine "frame, and the connecting link 3i is attached to a rod 86 (Fig. 3) carried at either end by an arm.37 free to root: upon the fulcrum rod27 of the segments 20. The springs 32 are connected respectively to the upper ends of the segments or quadrants 20 and to a rod 38 which extends on eithe side ot the connecting link 34:.

When in the normal position, the springs '32 are kept out of actions; the rock lever 33 under the infiuence'oii its counterweight rocks the arms 37 and the rod malres contact with the upper ends of the segments 20 and moves them into line so that all the type wheels 22 become" set at zero. The rock lever 33 is positively moved in the direction indicated by the arrow by of a link 39 joins, at its lower end in a manner well under seed to a foot treadle (not shownl, so that, when the treadle is depressed, the lever 33 will he moved wardly to withdraw the rod 36 from cent with the segments 20, and place the sp rii rants and rod 38.

wheel will mark three quarters.

32 under tension hctwcen the said quad-- the influence of their springs 32, swing on their pivot rod 327 and rotate the type wheels until the movementof each quadrant is arrcstei'l by the eontacting: of the sliding plungcrs 17 with the stcps 16 on the corresponding disks. These disks having been previously turned or rotated with the advance of the pointers to indicate the thickness and area nuaisurcmcnts, arrest the movement of the segments 20 when their type wheels are turned or set to the number which corrcspomls to the mimsurcment indicated hy the pointers. For instance. suppose the area iuiflir-ated is our and three quarters z.- rcprcsented in Fig. 4, then the plungers or slide rods 17 would make contact with their respective stepped edges at the point indicated hy the line /L in l ig. 5,

so that the tens type wheel will remain at zero, the units wheel will he moved to mark one unit. and the fractional or quarter The link 39 is pivoted at' its upper end to a short lever e0 loi'iscly mounted on the fulcrum 35 of the rock lever 33. This lever -10 carries at its end a pawl or dctent ill, arranged to cum c a notch or tooth ll on the rock lever i). when the lever ll; raised by the .link 3!). The rocking arms iii are connect ed to the link il hy means of a pin '2 and slot 4-3 the latter being; of sullicicnt length to allow the link 35) a ccrtain amount of free movement before it moves the rocking, arms 23 to lower the type wheels into contact with the material to stamp the same. This lree movement "s required to enable the link to actuate the rock lever 253 to release the (piadranl's, before the type wheels are lowcrei'l into contact with the material being; uicasurml and it may, as hereimrl'ter dcs-acrilnid perform other functions. .iiltcr the type wheels 921 have hecn set and sulrscqucntly lowin'cd to stan'ip the material with the uwasurerncnt imlicatcd the rear end of thcpawl or drtcnt l1 niakes contact with a lixcd pin ll. and said pawl is thereby disengaged 'lrom the notch or tooth 4], and the rock lever 33 being thus freed, is moved by its counterweight hack to the normal position and the quadrants return the type wheels to zero, as soon as said wheels are lil'tcd from the material. A suital'ile stop 4:5 limits the return. movement oi the rock lever 33. lfhuinn' the stamping or nun-king; ol' the material the latter is supported upon a bed or tahlc which receives it aitcr it has passed through the measurin mechanism of the machine.

This bed or table may he of any well known construction and arrangement such in! example as a traveling endless band 46 whose travel may be controlled by the foot lever which actuates the link 39, so that, before The quiulrimts, under the latter releases the swinging segments 30, the traveling bed 46 will he stopped 'in any suitahlc manner to bring the material to rest in the dcsired position under the type wheels 22. The rocking levers 21 and 7a arms 23 which support the segments 20 and type wheels 22 may he counterbalanced by weights 4-7 on the levers'i ll, and the pin and slot connection between the arms 23 and the link 39 as before descrihcdyallows the link to he moved a given distance bclore lowering the stamping wheels into contact with the material. The connecting means ll) intermediate of the sliding plum gel-s l7 and the swinging segments 20 are so adjustable in a suitable manner (for exam ple up and down the segments) so. that the rotation of the type wheels maybe set correctly relatively to the dilicrent steps 16 on the disks 11 and 13. 1 lVhat I claim is in.
